Wadsworth, Covington, Ky.Application June` 14, 1930. Serial No. 461,090 4 claims. (c1. 247-2)This invention relates to banking switch construction and has for anobject the provision of a. switch box which is especially adapted forboth independent and connected or banked installation. Another object isto provide a box of the type referred to wherein the switch isindependently mounted, vvfront operated Vfor' eifecting economy,oflspace and removable as a'unit. Another object is to provide a box ofthe class Areferred to wherein the side walls are entirely removable,interchangeable and replaceable by a connectork channel which permits ofbanking installation from either side of the box and at and access ofeach box.l 1 v Another object of this invention is to provide a boxofthe type referred to wherein the branch fuse circuits and theirassociated parts are mounted upon a swinging bridge structure hinged toa wall of the box independently of the lid and movable to a positionwhich renders the branch fuse side of the'box absolutely clear so thatwiring between adjacent banked switches of the invention may beinstalled entirely without inter'- ference and affording heretoforeunattained freedom for such work. 1

Another object is to provide a 'box of this kind wherein the vmetertesting switches are carried by the hingedly mounted branch fuse blockand operated with novel simplicity in a minimum of space.V

These and other objects are attained `by the means' described herein anddisclosed in the accompanying drawings, in which:

Fig; 10 is a perspective view of a pair of the boxes of the inventionconnected in banked arrangement with the structure shown in Fig. 7.

The box of the present invention provides for economy in manufacture aswell as in installation and connection. It will be noted that theoperating switch and line fuses are arranged in a small compact unitwhich is nevertheless entirely accessible and that the branch fusemounting and its associated parts are not only compactly arranged butare so disposed as t0 be swung entirely out of the box. The boxcomprises an apertured top wall 1,5, a bottom Wall 16 to which a flangedcover 1'7 is'hingedly mounted and a pair of similar side wall 18 havingflanges 19 on three sides thereof suitably slotted as at 20 to receiveinwardly extending lugs 21 on the top, bottom and rear walls of the box.The `resiliency of the sheet metal permits of surlcient spreading of thetop and bottom walls and 16 to position and remove the side Walls. Fromthe foref going it will appear that either or both of the side walls 18may be readily removed when the box is open, but that the lug and slotconnection between them and the box effectively precludes inadvertentseparation.

The connecting channel indicated generally as 272 comprises a base 23and flanges 24 all of which bear substantially the same relation to oneanother as the anges 19 on theside walls. The base 23 and ilanges 24have slots 25 therein positioned identically with the slots in theflanges of the side walls 18 whereforeit follows that the connectingchannel with the slots 25 adjacent "1' each side may be connected tothebox at either side by removing the side wall 18 and inserting theconnecting channel. In bank installations as shown in Fig.v `l0 theadjacent side walls 18 of adjacent boxes would be removed and a channelsuch as 22 inserted in the adjacent ends of said boxes. It will be notedthat the iianges 24 each have a substantially V-shapcd slot 26 at thetop. The closing trough, indicated generally as V2'7,

comprises a single piece of formed metal generally V-shaped in crosssection to seat in the slots and terminating at the top ina pair ofparallel wallportions 28. Formed on the lower V-shaped portion and ateach end is a pair of wings 29 which are adapted to embrace the outerfaces of .L
